Generic Case Extractor: Extended Export of Clinical Facts from i2b2

Abstract

Data import and export tools of the biomedical data warehouse system i2b2 (https://www.i2b2.org/) are restricted to its star schema and thus provide little flexibility. This is especially disadvantageous for external analysis with statistic software packages like SPSS or R. Further, data exports are limited to items previously selected within the query tool of i2b2. We present a tool for the case-oriented export of all clinical facts of a selected patient cohort into a CSV file for further analysis.
